Definitions

• the invention relates to a testing mould to test micro- and nano-coatings on A1 and Fe materials during product pressing, particularly in a vulcanisation mould.
• aluminium alloys are used to manufacture metal moulds for tyre production, especially for summer tyre moulds, or a combination of aluminium alloy and stainless-steel fins, especially for winter tyre moulds.
• the metal mould is composed of a certain number of segments, usually ranging from 8 to 36 depending on the size of a tyre being produced.
• the metal mould surface is not finished with any surface treatment technology.
• the moulds are used to produce tyres by vulcanising a mixture of organic substances at higher temperatures, i.e., 150°C to 170°C. After a certain number of cycles, i.e., the number of tyres produced, the individual segments of the metal mould are necessary to be cleaned.
• the test price for the testing mould for 2,400 pieces of mouldings is CZK 85,000; when testing directly on finished moulds, the price is CZK 510,000, i.e., 6 times more.
• the price of one finished mould for production is CZK 0.7 to 1.2 million; the price of the testing mould is only CZK 292,000.
• the testing mould comprises at least three Al-alloy testing inserts and three Al- alloy testing inserts with Fe fins having the same composition as the moulds for pressing the finished products themselves, wherein at least two Al-alloy testing inserts and at least two Al-alloy testing inserts with Fe fins are coated, i.e., six different variants in total.
• the testing inserts correspond to moulds for pressing finished products selected from the groups of tyres, shoe soles, and mats.
• the present invention introduces a so-called testing mould into the process of micro- and nano-coating; this mould is made of segments of the same composition as the moulds produced for the technology of manufacturing the finished products themselves, i.e., tyres, shoe soles, mats, etc.
• the advantage of the testing mould consists in those three different coatings on the inserts or two inserts with coating and one insert without coating are possible to be tested at the same time for comparison purposes, and this can be done in combination on the A1 mould only or the A1 mould with Fe fins.
• the complete assembled testing mould usually comprises three Al-alloy testing inserts and three Al-alloy testing inserts with Fe fins.
• the mould allows six different combinations to be tested at the same time within a single process, effectively reducing the financial cost of testing and examining multiple micro- and nano-coatings at the same time and comparing them to each other but also testing under the same conditions and shortening the overall process time.
• the testing equipment's low maintenance and cleaning requirements are also a great advantage.
• the ability to test and compare six variants simultaneously under exactly the same technical conditions also represents a great benefit.
• the cost of the produced testing mould is 3 to 7 times lower compared to the production of one mould for the finished production, wherein testing directly on the production mould is moreover impractical in terms of the exclusion thereof from the production process for a certain period, generating losses in production.
• FIG.l is an outline of the complete testing mould consisting of six testing inserts ready to test.
• FIG.2 is an outline of one of the testing inserts after coating.
• FIG.3 is an outline of moulding from the test of the testing mould.
• FIG.4a shows the mould in elevation and Fig. 4b in the side elevation.
• An exemplary testing mould to test micro- and nano-coatings on A1 and Fe materials during product pressing in a vulcanisation mould comprises three Al-alloy testing inserts and three Al-alloy testing inserts with Fe fins, which have the same composition as the moulds for pressing the finished products themselves, wherein two Al-alloy testing inserts and two Al-alloy testing inserts with Fe fins are provided with nano coatings.
• the testing inserts correspond to moulds used for pressing the fini hed products, i.e., tyres.
• the overall description and procedure of the vulcanisation mould production technology including the materials used for testing the micro- and nano-coatings, are specified in Table 1.
• the base plate for fitting the individual inserts is made by AlSilOMg material casting, followed by machining of the functional surfaces, par ticularly milling, turning, and drilling, to achieve the required surface quality and di mensional accuracy.
• the inserts six pieces in total, were produced by the low-pressure casting of AlMg4.5Mn material, subjected to heat treatment by hardening and me chanically machined by blasting before coating.
• the fin material is made of an alloy based on 1.4301, and the handles on the base plate are made of steel of grade 11.
• An example mould size is 400 x 380 x 54 mm, and the insert size is 90 x 100 mm.
• the testing mould to test micro- and nano-coatings on A1 and Fe materials during product pressing, in particular in a vulcanisation mould, according to the present invention will find the application mainly in the automotive and textile industries to test the moulds which have been coated during the manufacture of products made of vulcanisation compound, such as tyres, shoe soles, mats, etc.
